执行SHOW CREATE TABLE的MySQL存储过程?
要在存储过程中执行SHOW CREATE TABLE,请使用SHOW CREATE TABLE命令。让我们首先创建一个表 –
mysql> create table DemoTable2011
-> (
-> StudentId int NOT NULL AUTO_INCREMENT,
-> StudentName varchar(20),
-> StudentAge int,
-> StudentCountryName varchar(20),
-> PRIMARY KEY(StudentId)
-> );
Query OK,受影响的行数为0(0.80秒)
以下是执行SHOW CREATE TABLE的存储过程-
mysql> delimiter //
mysql> create procedure test_show_create_demo(table_name varchar(100))
-> begin
-> set @query=concat("SHOW CREATE TABLE ",table_name);
-> prepare st from @query;
-> execute st;
-> end
-> //
Query OK,受影响的行数为0(0.22秒)
mysql> delimiter ;
使用CALL命令调用存储过程-
mysql> call test_show_create_demo('DemoTable2011');
这将产生以下输出-

) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci |
